Math Problem Statement

Begin by graphing the standard quadratic function f(x) = x^2. Then use transformations of this graph to graph the given function h(x) = (x + 2)^2 + 5.

Solution

The question asks you to graph the function h(x)=(x+2)2+5h(x) = (x + 2)^2 + 5 by using transformations of the standard quadratic function f(x)=x2f(x) = x^2.

Step-by-Step Solution:

  1. Start with the base function: f(x)=x2f(x) = x^2, which is a parabola opening upwards with its vertex at the origin (0, 0).

  2. Apply the horizontal shift: The expression (x+2)(x + 2) indicates a horizontal shift. Since it is x+2x + 2, the graph shifts 2 units to the left.

  3. Apply the vertical shift: The +5+5 outside of the squared term indicates a vertical shift upwards by 5 units.

Determining the Correct Graph:

  • The vertex of the new function h(x)=(x+2)2+5h(x) = (x + 2)^2 + 5 will be at (2,5)(-2, 5).
  • The graph should be a parabola that opens upwards, shifted left 2 units and up 5 units from the original x2x^2 graph.

Looking at the Options:

  • Option A: Shows a graph with the vertex at (-2, 5), which matches the transformation.
  • Options B, C, and D: Do not match the correct shifts of left 2 units and up 5 units.

Conclusion:

The correct answer is A.

  2. How do you determine the direction of shifts from a function's equation?
  3. What is the effect of multiplying a function by a negative number?
  4. How does a vertical stretch or compression affect the graph of a function?
  5. What is the difference between a horizontal shift and a vertical shift?

Tip: Remember that a positive number inside the parentheses shifts the graph to the left, and a positive number outside shifts it upwards.
